this little thing showed up and doesn't want to go i tried everything i cant find any configure file i configure my hud via mod menu

It seems to happen when you join a world around the same time as a chat message is sent with Hide chat enabled and Show chat message indicator disabled. Enabling Show chat message indicator, waiting a few seconds for chat to clear, then disabling it again fixes the issue.
I can replicate it on singleplayer by setting up a repeating command block running say <message> then exiting and rejoining the world.

Interesting, thank you for the investigation! I will have a look.

tysm for the fix and amazing mod!

can confirm i have this issue aswell

Oh, I misunderstood. It gets stuck when it should never be rendered in the first place. I see, that makes some sense. I published a fix.

i solved the problem but god knows how.

If you can replicate this issue, please do let me know!

As of version 8.1, this bug has resurfaced. There may be mods posting welcome messages or debug info (e.g. DH) right after world load, making this happen reliably. Since updating AutoHUD to version 8, the chat indicator has been disabled but has not once disappeared for me, it's very annoying.

Try version 8.1.1, I believe I have fixed that today. It's only on CurseForge so far because Modrinth had issues today.
